  Nigerian currency notes, the naira, in circulation within the University of Agriculture, Makurdi Campus, were surveyed for microbial contamination. The viable count ranged between 8.4x104 and 7.2x105 colony forming units mL-1 of sterile water used in washing each note. The microorganisms isolated from the notes were Escherichia coli (80%), Aerobacter (59%), Salmonella (40.9%), yeast cells (36.4%), Streptococcus faecalis (31.8%), Staphylococcus aureus (27.3%) and coagulase-negative staphylococci (18.2%), Streptococcus faecalis (31.8%), Aerobacter (59%), Salmonella (40.9%) and yeast cells (36.4%). Contamination was significantly correlated with the denomination of the notes (r = -0.304; p = 0.019). Lower denomination notes were more contaminated than higher denomination notes (χ2 = 34.036; p = 0.03). Dirty and tattered notes had more contaminants than cleaner and newer notes (χ2 = 11.324; p = 0.01). This study has demonstrated that naira notes could be sources of contamination by microbial pathogens.
